Throughout the year, the UV Index exhibits significant seasonal variations. January and December see low UV levels (Index 2) where extended sun exposure is relatively safe, allowing for about 45 minutes before skin damage occurs. Moving into February and November, the index rises to moderate levels (Index 3 and 4), shortening burn time to 30 minutes. The UV Index peaks during the summer months, particularly from June to July, reaching a maximum of 10, categorized as very high with a burn time of just 15 minutes. April and May also register alarming UV levels (Index 8 and 9). March starts the transition with high levels (Index 6), leading into summer. August, while slightly lower at Index 9, maintains high risk, followed by September and October returning to high levels (Index 7 and 6) with longer burn times of 25 minutes. Residents and visitors should take necessary precautions, especially between March and October when the UV Index is highest.
